BASIC fails to force uppercase when program has compile error

[fredsa]

To reproduce:

1. Load a BASIC program
2. Modify the program to have an, for example type "x" on a line by itself
3. Reload the page

Expected:

• Text that you type is uppercase

Actual:

• Force upper case is disabled

Cause:

• Uppercase is only installed after successful compilation, in loadROM.

    loadROM(title, data) {
         …
        editors.textMapFunctions.input = this.program.opts.uppercaseOnly ? (s) => s.toUpperCase() : null;
         …
    }

And, loadROM is called only when there are no errors:

async function setCompileOutput(data: WorkerResult) {
  if ('errors' in data && data.errors.length > 0) {
        …
  } else {
        …
        await platform.loadROM(getCurrentPresetTitle(), rom);
        …
}

This is kinda tricky because we don't know the dialect and thus the uppercaseOnly setting until we successfully compile the program. What is happening is probably that the default BASIC dialect (when there's no program yet) has uppercaseOnly = false.
